And you also learned that the standard deviation on the stanford-binet scale is 15, not 10. :-) https://en.wikipedia.org/wiki/IQ_classification

Welcome to hacker news. Creating an account puts you up to 130 IQ minimum.

You're looking at it by statistical comparison, but the difference in capability may not actually be that large. Indeed, it's my perception that latent intelligence is far less important than knowledge gained through learning/experience.

My IQ was measured at 140 in high school, but having met a variety of people whose IQs I know, there are people with 100 IQ whose opinions I would defer to over my own, and people with 160 IQ whose opinions I would pretty much ignore. IQ just isn't a very important indicator of utility.
